Account for prefix, suffix, and separator space in the name. This
takes the effective length up to 229 bytes on 13-current, and 37 bytes
on 12-stable. 37 bytes is enough to hold a full GUID string.

We've not used this in years since we retired sysinstall, and it

Stop defining SMALLER. Since we replaced cpio with libarchive version,
there's no options to make it smaller. Also, the comment about the
FreeBSD installer is obsolete. Remove them both.
When the OpenBSD dhclient was brought in 14 years ago, we stopped
supporting building a reduced sized dhclient, yet retained the options
here. Also, the OpenBSD dhclient doesn't need lint defined, so it can
go too.
The reason for this is that ipftest(8), which still works on FreeBSD-11,
fails to link to it, breaking stable/11 builds.
ipftest(8) was broken (segfault) sometime during the FreeBSD-12 cycle.
glebius@ suggested we disable building it until I can get around to
fixing it. Hence this was not caught in -current.
The intention is to fix ipftest(8) as it is used by the netbsd-tests
(imported by ngie@ many moons ago) for regression testing.

BOOTP/DHCP and also uses RARP as a fallback. Problems with DHCP servers can
cause the loader to fail to populate network parameters.

When a command is finished running, we must transition it from INQUEUE
to busy state. We were failing to do that, so we hit a panic when the
commands were freed. This only affects mpr, mps already did simmilar
things. Now both the polling and interrupt paths properly set BUSY as
appropriate.
Summary:
Running a 32-bit process on a 64-bit POWER CPU may still use all 64-bits
in calculations, while ignoring the upper 32 bits for addressing
storage. It so happens that some processes end up with r1 (SP) having
bit 31 set in some cases (33-bit address). Writing out to this 33-bit
address obviosly fails. Since the CPU ignores the upper bits, we should
as well.
sendsig() and cpu_fetch_syscall_args() appear to be the only functions
that actually rely on userspace register values for copy in/out, and
cpu_fetch_syscall_args() doesn't seem to be bitten in practice yet.

instructions or operations they are stored in an integer called
addrem (add/remove). 1 is add, 2 is remove, and 3 is clear stats and

operations by replacing simple integers with a self documenting

Instead of including stdint.h for uintptr_t, include sys/_types.h and use
__types for everything that isn't a native C keyword type.
Remove the #include of cdefs.h. It appears after the include of armreg.h
which has a precondition of cdefs.h being included before it, so everyone
including sysarch.h is already including cdefs.h. (When armv5 support
goes away, there will be no need include armreg.h here either.)
Unfortunately, the unprefixed struct member names "addr" and "len" cannot
be changed, because 3rd-party software is relying on them (libcompiler_rt
is one known consumer).
On POWER9/pseries, QEMU passes several regions of memory,
instead of a single region containing all memory, as the
